Richardson was chosen 20 years after he coached Arkansas to a national championship. Williams won a title with Maryland in 2002.

Former NBA star Mitch Richmond also was part of the class that was announced Monday. They will be inducted at a ceremony Aug. 8 in Springfield, Mass., along with members who were already announced, including retired NBA Commissioner David Stern.

Richardson’s Razorbacks beat Duke for the 1994 title and made two other trips to the Final Four. Williams and the Terrapins beat Indiana for the title 12 years ago.

Lithuania star Sarunas Marciulionis was among several candidates already selected by various committees.
